摘要:
Two silver(I) complexes with heterocyclic thione, [AgCl(PPh3)(2)(BTZT)](2) (1) and [Ag(PPh3)(2)(BTZT)(2)](NO3) center dot CH3OH (2) (PPh3=triphenylphosphine; BTZT=benzothiazoline-2-thione) have been synthesized and characterized by IR, single-crystal X-ray diffraction, fluorescence spectrum and H-1 NMR spectroscopy. Heterocyclic thiones possess chemically active groups -N(H)-C(=S)- in equilibrium with its thiol form. 1 and 2 are obtained by the reactions of AgCl or AgNO3 with PPh3 in the presence of 2-mercaptobenzothiazole (MBT) in mixed solvent (CH3OH/CH2Cl2). The complex 1 contains two same structures in each asymmetric unit, but there are different bond lengths and bond angles. Complex 2 is a simple mono-nuclear heteroleptic complex whose main structure links free CH3OH and NO3- anion by hydrogen bonding interactions. The red-shift of emission peak of 1 similar to 2 is derived from ligand-centered pi-pi* transition. CCDC: 1059719, 1; 1059720, 2.
